BACKGROUND OF THE INVENTION

[0002] 1. Field Of The Invention

[0003] This invention is directed to: buildings and parts thereof; portable buildings with one or more monolitihic walls and/or floor; and to roofs for buildings which, in one aspect, are roofs for portable buildings, the roofs having one or more interior supports, enclosures, wire ways, or chases for wires, cables, etc, connected to or formed integrally of the roof. In one particular aspect, parts of such a building are made of bullet-resistant or bulletproof materials, including, but not limited to windows, walls and/or floors.

[0004] 2. Description of Related Art

[0005] The prior art discloses a variety of portable buildings and buildings assembled from prefabricated building elements. Many such buildings have been used for various functions in a variety of industries.

[0006] It is known in the art to place a single-piece roof structure or truss system on the walls of a portable building and to secure it to the walls, and to cover the top and outer sides of such a roof structure with a layer or membranes of protective material such as rubber, rubber roof membrane, flexible plastic, elastomeric material, and fiberglass. Prior art roof trusses are made of metal (e.g. aluminum or steel), wood, fiberglass or some combination thereof.

[0007] In certain prior art systems, one or several pieces or panels of roof covering or “membrane” material are installed on top of a roof; and, when multiple pieces are used, to join and seal them together. Such roof coverings are secured to the underlying roof by adhesives, or other suitable fasteners. In certain prior art a fiberglass covering is used, and in others the edges or joints between a roof covering and an underlying roof are sealed with a separate member (e.g. a flashing or batten). The top edges of vertical walls on which the roof is to be positioned are covered with a protective apron. With other prior art roof structures a metal plate is used on the top outer edge of the structure to seal abutting members used to make the roof structure. In one prior art system a trough or support is attached around the vertical walls and a lower edge of the roof is received and held in the trough or support.

[0008] In various prior art systems interfaces between roof and walls and between roof holders or supports and a roof need to be sealed, often requiring the use of an additional member. The use of roof holders, e.g. “J” rails, requires the emplacement and attachment of the “J” rails to the walls.

[0009] There has long been a need for buildings and parts thereof, including portable buildings, with a minimum number of components. There has long been a need, recoginized by the present inventor, for an efficient and effective monolithic building component (e.g., for a wall or floor) for portable buildings. There has long been a need, recoginized by the present inventor, for an efficient and effective roof structure that includes structure for supporting wires, etc.

DESCRIPTION OF EMBODIMENTS PREFERRED AT THE TIME OF FILING FOR THIS PATENT

[0046]FIG. 1A shows a roof structure 10 according to the present invention with a roof covering 20 and a roof truss 30 therein. The roof covering 20 has ends 21 and lower lips 22 that project in from opposed sides 24 beneath a bottom 32 of the roof truss 30. A top 26 spaces apart the sides 24. The roof covering 20 is a single piece made separately that is placed on and then glued to the roof truss 30.

[0047] In another embodiment the roof covering 20 is initially made up of separate pieces of material placed on the top and sides of the roof truss 30. Edges of the pieces are sealed or welded together to form an integral covering.

[0048] The roof truss 30, FIG. 1C (which is within the roof covering 20 in FIG. 1A), has sides or aprons 33, ends 34, internal rafters 35 and supports 37, and a top member 36. In one aspect the top member 36 is eliminated.

[0049] The lip 22 may be larger or smaller than shown. It is within the scope of this invention for the lip to project inwardly to contact a building wall and, in one aspect, to extend downwardly to cover part of the wall. Alternatively, part of the roof covering 20 may extend upwardly between the roof truss 30 and a wall of a building. The roof covering 20 may be any desired thickness and, in certain preferred embodiments, ranges between 0.025 inches and 1.00 inches thick. In one particular embodiment the roof covering 20 is commercially available rubber roof membrane material about 0.065 inches thick.

[0050] As shown the ends 34 of the roof truss 30 are covered by the roof covering 20. It is, however, within the scope of this invention for the roof covering not to cover the ends 34 or to partially cover them. Alternatively, separate pieces of membrane material may be applied to the ends 34. In one aspect such pieces are sealingly joined at their edges to the roof covering 20.

[0051]FIG. 2A shows a building 50 according to the present invention with walls 52 (two shown); a floor 54; and a roof system 60 according to the present invention.

[0052] The roof system 60 has a truss 62 and a roof covering 64 on the truss 62. The roof covering 64 has a roof member 66 and lower lips 68 that project beneath edge members 61 of the truss 62. The lips 68 also extend down over and are glued to a top portion 53 of the walls 52. Screws 70 (or other suitable fasteners) are used to secure the roof covering 64 to the truss 62. Such fasteners may also extend through the lips 68 into the walls 52. Alternatively, or in addition to the screws 70, adhesive may be used.

[0053]FIG. 3A shows a top view of a roof structure 100 according to the present invention covered by flexible roof covering material 102. FIG. 3B is a bottom view of a truss 104 used beneath the roof covering material 102 of the roof structure 100. The truss 104 has a top 112, interconnected sides 108 and 110, and cross-supports or rafters 106.

[0054]FIG. 3C is a cross-sectional view through the roof structure 100 (showing both a vertical and a horizontal view through the roof structure 100 as shown in FIG. 3A). The roof covering 102 covers the top 112 of the truss 104, its sides 108 and 110 and a portion of inner side surfaces 116 and 118. It is within the scope of this invention for the covering to cover only one inner side surface or any two opposed inner side surfaces.

[0055]FIG. 3D shows a cross-sectional view of the roof covering of the roof structure of FIG. 3A. FIG. 3E shows a cross-sectional view of the roof truss of the roof structure of FIG. 3A.

[0056] In addition to the use of flexible material, flexible plastic, flexible fiberglass, or flexible fabric for any roof covering herein, alternatively any suitable spray-on water-repellent material may be used to produce a roof covering according to the present invention, including, in one aspect, spray-on thermoplastic polyurethane material and spray-on thermoplastic polyurethane/polyurea material (referred to collectively as “protective material”)—which may also, according to the present invention, be used as covering for a building's floor and/or walls (e.g. but not limited to Line-X™ sprayable materials, BUC XS-350, BUC XS-13, BUC XS-17, BUC XS-Series, and BUC XS-100 sprayable material, commercially available from Burtin Corporation). In one aspect the spray-on material substantially covers one or both primary surfaces of the roof, floor, and/or walls and, optionally, edges thereof. The spray-on covering may be sprayed onto the roof, floor and/or walls either prior to building assembly or thereafter.

[0057]FIG. 4 shows a building 150 (in cross section) with a roof structure 100. The building 150 has four walls 152 (three shown) and a floor 154. An upper portion of the walls is in contact with a portion of the roof covering 102 disposed between an exterior of the walls and an interior of the roof truss 104. This portion of the roof covering serves as a sealing gasket between the walls 152 and the roof structure 100.

[0058]FIGS. 5A and 5B show a roof structure 160 like that in FIG. 4 with a truss 161, but with flexible plastic, fiberglass, fabric, or rubber roof membrane material 162 (preferably water-repellent) (collectively “roof material”) covering both the exterior surfaces (top 164, sides 166) and the interior surfaces (ceiling 167, sides 168) as well as the lower ends 169 of the sides. Another difference is the use of L-shaped protectors 170 with a lower flat part 172 over the ends 169 of the roof structure 160 and an upper vertical part 174 on the interior sides 168. As shown in FIG. 5B, the protectors 170 cover all the lower end surfaces with the exception of the corners. It is within the scope of this invention for the protectors 170 or for any of the protectors 170 to extend over only a portion of a lower end 169. It is also within the scope of this invention to glue or fasten a solid protective piece on the uncovered corners (see FIG. 5B). Alternatively, the upper vertical part 174 of any of all of the protectors 170 may be on the outside of the roof structure 160.

[0059] The protectors 170 (and any protector or angle piece in FIGS. 5A-8B) to be made of a suitable thickness that will not interfere with the emplacement of a roof structure on the walls of a building and to be made of any suitable solid, tape, or foil material, including, but not limited to, aluminum sheet or foil, flat fiberglass pieces, sheet metal, or plastic. The protectors may be glued on (see, e.g., the protector 170 on the left side of FIG. 5A) or they may be attached with a fastener (see, e.g., the screw 171 through the protector 170 on the right side of FIG. 5A). Appropriate adhesives or adhesive tape may also be used to hold the protectors in place. In one aspect the protectors or angle pieces may be thinner than the roof material.

[0060]FIG. 6 shows a roof structure 180 according to the present invention with a truss 181 and roof membrane material 182 covering the exterior surfaces (top 183, sides 184, ends 185) and a portion of the interior surface (sides 186). U-shaped protectors 187 cover the ends 185 and extend all around the roof structure 180 (as do the protectors 170 in FIG. 5B). For fluid drainage, the protectors 187 may have one or more holes 188. FIGS. 5A-8B are schematic and the thicknesses of various items shown are merely illustrative. Any suitable thickness of roof membrane material or of protector material may be used. The protectors 170 have two members at a right angle to each other and the protectors 187 have three members. It is within the scope of this invention for the protectors (and angle pieces, FIG. 7) to be integral pieces or made up of separate pieces each individually adhered to, attached to, and/or connected to (e.g. with fasteners or Velcro™ material). From below, the roof structures of FIGS. 6-8A look like that of FIG. 5B (or any of them may be rectangular, trapezoidal, circular, triangular or any desired shape).

[0061]FIG. 7 shows a roof structure 190 according to the present invention with a truss 191 covered exteriorly and partially interiorly with flexible roof material 192. Attached to a ceiling 193 and interior sides 194 with screws 195 are angle pieces 196. The screws 195 extend through the roof material 192. Instead of, or in addition to the screws, suitable adhesives and/or tape may be used. The angle pieces may be the length of the interior sides or some shorter length. If the length is shorter, one, two, three, four or more may be used on each side. The protectors, angle pieces, and attachment pieces disclosed herein may be the same thickness as the roof material or they may be thicker or thinner than the roof material.

[0062]FIGS. 8A and 8B show a roof structure 200 according to the present invention with a truss 201 and roof material 202. End portions 205 of the roof material 202 hang over attachment pieces 203 adhered to the roof material and/or affixed to the truss sides with screws 204. As shown in FIG. 8B, the end portions 205 are disposed between a lower surface 207 of the truss 201 and upper ends 208 of walls 210 of a building 211 having a floor 212. The end portions 205 serve as a gasket and/or seal. The attachment pieces may be any suitable solid, soft, or flexible material and may also serve as a gasket or seal between the roof structure and walls. The building 211 represents any building suitable for emplacement thereon of a roof structure 200. The roof material 202 may be any desired thickness and the end portions 205 may be any desired length, i.e., the end portions 205 may extend beyond the top of the attachment pieces 203 any desired length. Alternatively, one, two, three, four or more thicknesses of the roof material 202 may be folded on themselves and secured to the lower surface 207 of the truss 201 to serve as a seal and/or gasket.

[0063]FIG. 9 shows a building 220 (exploded view) according to the present invention which is like a prior art building except for covering material, which in one aspect is spray-on material on the components of the building. The cross-hatching on the various components indicates coating, e.g. a layer of sprayed-on material, e.g., but not limited to, a layer of sprayed-on thermoplastic polyurea or sprayed-on thermoplastic polyurethane/polyurea. In one aspect the coating of such sprayed-on material is applied by known apparatus to a desired thickness, e.g. between about {fraction (1/16)}″ to ⅜″. A floor 222 rests on a support 224 (which can be any known skid, foundation, or support). The floor 222 has a coating 223 of covering material. Optionally an underside of the floor 222 is also coated with the covering material and/or edges 221 are similarly, optionally, coated as, optionally, are the edges of the other components of the building 220. The support 224 has a coating 225. An underside surface of the support 224 may also be coated. An interior surface 227 of each side walls 228 is coated with coating 226 and, optionally, outside surfaces 229 may also be coated with a coating 230. An interior surface 231 of an end wall 230 is coated with a coating 233 and, optionally, an exterior surface 232 is also coated with a coating 237. A roof structure or truss 236 has a top coating or layer 239 and its sides 235 are also coated with a coating 237. An underside of the roof truss 236 may also be coated. Alternatively, only exterior surfaces of the building 220 may be coated, prior to or following assembly. An end wall 250 with a door opening 256 has an exterior surface 252 with a coating 254. The interior of the end wall 250 may also be coated.
